Answer:

1. 80º

2. Both are 54º

Explanation:

1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º

2. Just like in the first one, we need this to equal 180º. So, let's go backwards.

180 - 72 = 108

Now, since the remaining angles are equal, let's divide 108º by 2

108 / 2 = 54º

Hope this helps :)
